Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, specifically to a cutting and slitting device for circuit board processing. Background Technology

[0002] Circuit boards are the basic components of electronic devices. One of their main purposes is to provide electrical connections for electronic components. Conductive lines formed on circuit boards through processes such as etching or printing can connect various electronic components (such as chips, resistors, capacitors, inductors, etc.) according to the designed circuit schematic. In the production process, the original circuit board material (such as copper-clad laminate) is usually a large board material. Different electronic devices have different requirements for the size of the circuit board. One of the purposes of cutting and cutting the board is to cut the large original board material into small circuit boards that meet the design size of specific products.

[0003] In the prior art, patent CN 222235147 U discloses a board cutting device for circuit board processing, including a worktable, a pushing and feeding mechanism, a support, a width positioning mechanism, a frame, a head position adjustment mechanism, a cutting mechanism, an automatic unloading mechanism, a receiving box, and a pointer. The head position adjustment mechanism is installed on the left end of the worktable. The head position adjustment mechanism includes a first hydraulic cylinder, a positioning baffle, and a scale. The first hydraulic cylinder is fixed on the worktable, and the output end of the first hydraulic cylinder is fixed to the positioning baffle. A scale is installed on the positioning baffle. The pushing and feeding mechanism is installed at the bottom of the worktable and extends to its upper side. The support is fixed on the worktable, and the width positioning mechanism is installed on the support. The frame is installed on the left half of the worktable, and the cutting mechanism and the automatic unloading mechanism are installed on the frame. A receiving box is set on the ground opposite the automatic unloading mechanism.

[0004] However, the above solutions only consider the collection of materials after circuit board cutting, but do not consider the treatment of circuit board waste generated during the cutting process. If the debris, scraps and other waste generated during the circuit board cutting process are not cleaned up in time, they may accumulate on the workbench, affecting subsequent circuit board processing, or even entering mechanical parts and causing wear and tear on the parts. Therefore, we propose a cutting device for circuit board processing. Utility Model Content

[0010] Furthermore, the waste collection mechanism also includes a small handwheel and a tightening bolt. The tightening bolt is threaded into the threaded hole at the right end of the adjusting frame. The front end of the rotating shaft is provided with a small handwheel for adjusting the angle of the suction head.

[0011] Furthermore, the front side wall of the waste bin is hinged with a waste door, the left side wall of the waste bin has an exhaust hole, the right edge of the exhaust hole has a partition, the left edge of the exhaust hole has an exhaust pipe, and the exhaust pipe passes through the left side wall of the workbench for drainage.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6This embodiment provides a technical solution: a board cutting device for circuit board processing, including a workbench 1. A control switch group 18 is provided on the front side of the workbench 1. The input terminal of the control switch group 18 is electrically connected to an external power source. A cutting frame 7 is provided on the upper side of the workbench 1. An electric cylinder 8 is mounted on the upper side of the cutting frame 7. The telescopic end of the electric cylinder 8 passes through the upper end of the cutting frame 7. A cutting blade holder 9 is fixedly connected to the telescopic end of the electric cylinder 8. The input terminal of the electric cylinder 8 is electrically connected to the output terminal of the control switch group 18. The lower... The worktable 1 is equipped with an adjustable cutting blade holder 9 at one end, and a cutting blade 10 at the lower end of the cutting blade holder 9. A guide frame 11 is provided on the upper side of the worktable 1. A double-acting lead screw 12 is rotatably connected between the front and rear inner walls of the upper end of the guide frame 11. Guide plates 15 are threadedly connected to both ends of the double-acting lead screw 12. A guide groove 14 is provided in the middle of the guide frame 11, and the middle parts of the guide plates 15 are slidably connected to the interior of the guide groove 14. A handwheel 13 is provided at the front end of the double-acting lead screw 12. An electric cylinder is mounted on the upper side of the worktable 1 via an electric cylinder frame. The electric telescopic rod 16 has a push plate 17 at its telescopic end. The input end of the electric telescopic rod 16 is electrically connected to the output end of the control switch group 18. The worker places the original circuit board material between two guide plates 15. Then the worker rotates the handwheel 13. The rotation of the handwheel 13 drives the bidirectional lead screw 12 to rotate synchronously. Under the rotation restriction of the thread of the bidirectional lead screw 12 and the guide groove 14, the two guide plates 15 move inward at the same time and contact the front and rear sides of the original circuit board material. Then the worker operates the control switch group 18 to make the electric telescopic rod 16 run. The telescopic end of the electric telescopic rod 16 pushes the push plate 17 to move to the left at a uniform speed. At this time, the push plate 17 pushes the original circuit board material to the left. When the original circuit board material moves to below the cutting blade 10, the worker operates the control switch group 18 to make the electric cylinder 8 run. The telescopic end of the electric cylinder 8 pushes the cutting blade holder 9 downward. The cutting blade holder 9 drives the cutting blade 10 to move downward until it cuts the original circuit board material, which facilitates the cutting of the circuit board. It also includes a waste collection mechanism 2.

[0026] Waste collection mechanism 2 includes an adjusting frame 21, a rotating shaft 22, a dust suction head 25, and a waste bin 29. The adjusting frame 21 is located on the right side of the cutting blade holder 9. The rotating shaft 22 is rotatably connected to the right end of the adjusting frame 21. The dust suction head 25 is located at the rear end of the rotating shaft 22. The waste bin 29 is installed on the top wall of the workbench 1. The interior of the waste bin 29 is equipped with an inclined plate 4. The front side wall of the waste bin 29 is hinged with a waste door 3. The left side wall of the waste bin 29 has an exhaust hole. A partition 6 is located at the right edge of the exhaust hole, and an exhaust pipe 5 is located at the left edge of the exhaust hole. The exhaust pipe 5 penetrates the left side wall of the workbench 1. The waste bin 29 is installed in conjunction with the dust suction head 25. The waste collection mechanism 2 also includes a telescopic hose 26, a collection pipe 27, and a fan. 28. A collection pipe 27 is provided on the rear wall of the waste bin 29. A telescopic hose 26 is provided on the lower front end of the collection pipe 27. The lower end of the telescopic hose 26 is fixedly connected to the upper end of the suction head 25. The telescopic hose 26 is connected to the suction head 25. A fan 28 is connected in series in the middle of the collection pipe 27. The input end of the fan 28 is electrically connected to the output end of the control switch group 18. The waste collection mechanism 2 also includes a small handwheel 23 and a tightening bolt 24. The tightening bolt 24 is threaded into the threaded hole at the right end of the adjusting frame 21. A small handwheel 23 is provided at the front end of the rotating shaft 22. Before cutting the original circuit board, the worker turns the small handwheel 23, which drives the rotating shaft 22 to rotate. At this time, the suction head 25 also rotates. When the suction head 25 is aligned with the original circuit board... The cutting blade makes pre-contact with the original circuit board material, and then the tightening bolt 24 is tightened. The tightening bolt 24 tightens the rotating shaft 22, making it difficult for the rotating shaft 22 to rotate, thereby maintaining the current position of the suction head 25 (when the angle of the suction head 25 is adjusted, the telescopic hose 26 is partially folded; during the cutting of the original circuit board material, as the cutting blade holder 9 moves the cutting blade 10 downward, the telescopic hose 26 extends and retracts). Then, the worker operates the control switch assembly 18 to start the fan 28. The fan 28 sucks up the waste generated during the cutting of the original circuit board material through the complete channel formed by the collection pipe 27, the telescopic hose 26, and the suction head 25, and then discharges it into the waste bin 29 through the collection pipe 27. When the waste gas mixes... After the material enters the waste bin 29, the partition 6 isolates the solid waste. The gas passes through the partition 6 and is discharged from the exhaust pipe 5 of the waste bin 29. The solid waste slides down naturally through the inclined plate 4. The worker opens the waste door 3 to collect the waste. A large amount of debris is generated during the circuit board cutting process. The dust collection device can promptly suck up these debris. The adjustable dust head angle can flexibly align the cutting blade with the original circuit board material. When processing circuit board materials of different thicknesses, the height of the debris will be different. The adjustable dust head can adjust the angle to keep the dust inlet at a suitable distance and angle from the debris source of different heights, ensuring that the debris can be effectively collected regardless of the thickness of the original circuit board material, and ensuring that the cutting work of the original circuit board material is not interfered with by debris.

[0027] The working principle of the circuit board cutting device provided by this utility model is as follows: First, the worker places the original circuit board material between two guide plates 15. Then, the worker rotates the handwheel 13, which drives the bidirectional lead screw 12 to rotate synchronously. Under the rotation restriction of the thread of the bidirectional lead screw 12 and the guide groove 14, the two guide plates 15 move inward simultaneously and contact the front and rear sides of the original circuit board material. Then, the worker operates the control switch group 18 to operate the electric telescopic rod 16. The telescopic end of the electric telescopic rod 16 pushes the push plate 17 to move to the left at a constant speed. At this time, the push plate 17 pushes the original circuit board material to the left. When the original circuit board material moves to below the cutting blade 10, the worker operates the control switch group 18 to operate the electric cylinder 8. The telescopic end of the electric cylinder 8 pushes the cutting blade holder 9 downward. The cutting blade holder 9 drives the cutting blade 10 to move downward until the original circuit board material is cut. Before cutting the original circuit board material, the worker rotates the small handwheel 23, which drives the rotating shaft 2. 2. Rotation: At this time, the suction head 25 also rotates. When the suction head 25 is aligned with the pre-contact area between the cutting tool and the original circuit board material, the tightening bolt 24 is then tightened. The tightening bolt 24 tightens the rotating shaft 22, making it difficult for the rotating shaft 22 to rotate, thereby maintaining the current position of the suction head 25 (when the angle of the suction head 25 is adjusted, the telescopic hose 26 is partially folded. When cutting the original circuit board material, the telescopic hose 26 extends and retracts as the cutting tool holder 9 drives the cutting tool 10 to move downward). Then, the worker operates the control switch group 18 to make the fan 28 run. The fan 28 sucks up the waste generated during the cutting of the original circuit board material through the complete channel composed of the collection pipe 27, the telescopic hose 26, and the suction head 25. Then, it is discharged through the collection pipe 27 into the interior of the waste bin 29. When the waste gas mixture enters the waste bin 29, the partition 6 isolates the solid waste. The gas passes through the partition 6 and is discharged from the exhaust pipe 5 of the waste bin 29. The solid waste slides down naturally through the inclined plate 4. The worker opens the waste door 3 to collect the waste.

[0028] It is worth noting that the electric cylinder 8 and the electric telescopic rod 16 disclosed in the above embodiments can both be model FY020, the fan 28 can be model CX-75SA, and the control switch group 18 is provided with control buttons that correspond one-to-one with the fan 28, the electric cylinder 8 and the electric telescopic rod 16 and are used to control their switching.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
